Player Assigned Random Number Generators for Gaming Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Players in wager-based gaming systems face issues with perceived trends in game outcomes, leading to unfair advantages and disadvantages due to shared random number generators (RNGs) across multiple users, causing concerns about game hotness and jackpot probabilities.
Innovation Solution
Assigning unique RNGs to individual players, allowing each player to have dedicated random number sequences for game outcomes, and enabling RNGs to be stopped and restarted for continuous sequences across sessions, ensuring each player's experience is independent and unique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a shared RNG is used across multiple players, then device complexity is reduced, but player experience fairness deteriorates due to perceived trends and hot/cold machine beliefs
Solution Approach 1:
The patent divides the shared RNG system into multiple player-specific RNG instances. Each player is assigned their own dedicated RNG that generates independent random sequences, eliminating the shared pool that caused perceived trends. This segmentation maintains fairness while managing complexity through systematic player-RNG mapping.
Solution Approach 2:
The system pre-assigns specific RNG instances to players before gameplay begins. This preliminary assignment ensures that each player has a dedicated RNG from the start, preventing any perception of outcome manipulation or trending that would occur with dynamic or shared RNG allocation.
2Ease of operation
If a player's RNG sequence is continuous across sessions, then player convenience is improved, but system complexity increases due to state management requirements
Solution Approach 1:
The system saves the RNG state at the end of each player session and restores it at the beginning of the next session. This preliminary state preservation allows the RNG sequence to continue seamlessly across sessions without requiring complex real-time synchronization, maintaining both convenience and manageable complexity.
Solution Approach 2:
The patent implements state persistence by copying and storing the RNG state data between sessions. This copying mechanism allows the system to reconstruct the exact RNG state when a player returns, ensuring continuous sequences without requiring the RNG to remain actively running, thus balancing convenience with system efficiency.
3Productivity
If gaming machines are time-shared among multiple players, then productivity is improved, but player experience quality deteriorates due to shared outcomes and perceived trends
Solution Approach 1:
The patent segments the gaming machine's RNG resource into multiple player-specific instances. When players time-share the physical machine, each player's gameplay is driven by their own dedicated RNG, ensuring that outcomes are independent and not influenced by other players' sessions. This segmentation enables high machine utilization while maintaining individualized player experiences.
Solution Approach 2:
The system performs preliminary RNG state saving and player identification procedures when a player begins a session. This preliminary setup ensures that the correct player-specific RNG is activated and that the sequence is properly initialized or restored, maintaining experience quality during time-shared operation.
Data Source
AI summary
Gaming machines utilize the output of random number generators (RNGs) in the presentation of games, wherein one or more of the RNGs is each assigned to a single player. Each uniquely assigned RNG is used to determine the outcome of the games played only by the assigned player, such as games presented by casino gaming machines or via remote or mobile devices. An RNG may also be stopped or paused and then restarted, whereby a sequence of random data remains continuous or contiguous relative to a number of games played, such as by the single player to which the RNG is assigned. Multiple players may also time-share a gaming machine in a manner whereby the gaming machine acts as a unique device to each player.
